CAN-CAP LACQUERING OR COATING MACHINE.

' Specification of Letters Patent. Application filed m 1:, 1908. Serialno. 4.32.691.

provide an automatic machine of a simple, efiicient' and durableconstruction, by, means of which the inner faces of can caps mayrapidly, and cheaply lined or coated with lacquer or other protectivecoating.

The machine embodying my invention comprises in cooperative combinatiomaplurality of spraying devices, a. plurality of can cap magazines orhoppers, a plurality of can 2 cap feeders, a plurality of can caplifters,

a plurality of can cap holder spiders or carriers furnished with apluralityv of rotatable can cap holders, means for rotating the holderson each when each in turn is brought into cooper- 'ative relation withthe spraying devices, stripping or ejecting devices for stripping thesprayed caps from theholders and deliv-- erin the same with their coatedfaces upwar to adrier and a conveyer for moving the coated caps in or onthe drier. My invention consists in the novel construction of parts anddevices and inthe novel combinations of parts and devices herein shownor described.

In the accompanying drawing forming a part of this specification, Figurel is a p an view of a can cap lacquering or coating machine embodying mymventron, a ortion of the drying mechanism bein bro en away.

- In the drawing, A represents the frame of Patented Jan. 9,1912;

the machine, B the sprayheads or spraying devices, C the cap magazinesor hoppers, D the reciprocating cap feeders, E the vertically movablecan cap lifters, F the rotating can cap holders, G the intermittentlyrotating carriers or spiders upon which the rotatable cap holders. F arejournaled or mounted, H the devices for rotating the cap holders, K thestrippers or ejecting devices for removing the freshly coated caps fromthe holders, K the connecting chute for delivering the freshly coatedcaps to the drier, M the drier, M the conveyer of the drier, N thesupply,ta'nk for-the liquid lacquer or coating material 1 and P thevalves or devices for automatically regulat-in and controlling theamount of liquid acquer or coating material sprayed upon each can cap.

In the drawing I have shown the preferred construction of. each of theprincipal parts or devices which are combined together to embody myinvention in an automatic machine. Each of the spray heads or sprayingdevices B consists essentially of a liquid chamber 6 formed by a pipe orcasing 6 an air chamber 1) formed by a pipe or casing b, a plurality ofupright or vertically disposed liquid nozzles or nipples 6*, preferablythree in number, and a corresponding series or plurality of horizontallydisposed air-blast nozzles b arran ed substantially at right angles tothe liquid nozzles.

The liquid chamber pipe or casing b has a contracted overflow ordischarge so that the liquid lacquer or coating material may constantlyfill the same and thus be maintained at a constant level in respect tothe lower ends of the liquid'nozzles b. The liquid lacquer or coatingmaterial flows from the .supply tank N into the liquid chamber 1) pipeI) and overflows from said l1qu1d chamber I) through the overflow pipe 6into a drip which it is pumped back into the supply tank N through thereturn pipe N by a pump N". Preferably a single liquid cham ber casingor pipe I) may be employed for each group of liquid nozzles or sprayheads. A separate air chamber casing 6", however,

through a supply tank N from is preferably employed for each group &

v by branch pipes b", each of which is furnlshed with a pressureequalizer enlargement or couplin b and with a valve or pressurecontrolling device Pi Each of the can cap magazines or hoppers Cpreferably consists of an open bottom cylinder conforming in mteriordiameter to the exterior diameter' of the can caps X, which are placedin the magazine with their outer faces uppermost so that the inner faceof each cap which is to receive the lacquer or protective coating willbe lowermost.

The can cap feeders D each preferably consists of a reciprocating slide,having a lip or shoulder d, adapted to engage the lowermost cap only inthe magazine C and slide it forward over thecap lifter E. The cap feederD reciprocates back and forth on a suitable guideD on the stationaryframe of the machine, and is preferably operated by a cam r on the camshaft R through the connecting link (5 lever d and connecting linkd a.Each of the cap lifters E preferably consists of a verticallyreciprocating head i which is moved up and down by means of a cam R onthe cam shaft R, which engages bar E on the stem E of the cap lifter E.The cap lifter E serves to lift or raise each can ca upward so that itwill beproperly graspe by the rotatable cap holder F- on the carrier Gwhen the feeder D moves the cap X over the lifter E; l

Each of the rotatable can cap holders F preferably consists of apermanent electromagnet secured in a rotatable head F, the

shaft or spindle f of which is journaled in the arm 9 of the carrier orspider G, and is furnished with a bevel friction gear or wheel f adaptedto engage a suitable friction wheel or device H for rotating the holderand the cap when the carrier G moves the holder F and can cap thereoninto cooperative relation with the vice or headB.

Each of the carriers or spiders G is preferably furnished with four armsg, and thus carries four of the rotatable holders F so that the severalholders F on each carrier or spider G will have their axes at rightangles to each other, and so that one holder F may be in an uprightposition suitable for receiving a cap from the lifterE while anotherholder F will have its axis horiing the cap thereon to the spray head Band rotating it in a vertical plane. riers or spiders G are preferablyfour'in number, corresponding with-the number of the spray heads B andthey are all mounted upon or secured to the same operating shaft G whichis intermittently turned by any suitable operating mechanism, the same Ihead F spraying dezontal and in proper position for present- Thecargaging preferably consisting in a crank arm 1' on" erating mechanismof the carriers G to bring the holders F accurately into register withthe cap lifter E and spraying head B;

Each of the devices H for automatically rotating the cap holders Fpreferably consists of a conical or friction gear or wheel secured to ashaft H and arranged in cooperative relation to the friction gear orwheel f on the spindle of the cap holder when the carrier G brings eachcap holder F into position for cooperation with the spray head B. Theshaft H of the cap holder rotating devices H is preferably continuouslyrotated by means of a pulley h on said shaft H and a belt 72, and pulleyh on the driving shaft S. v

The strippers or ejecting devices K for stripping or discharging thefreshly coated caps X from the magnetic cap holders F as the carrier Grotates, preferably consist of curved fingers secured to or formedintegral with the connecting chute K and projecting, from the upper edgethereof and adapted to fit astride the cap holders F and engage theouter edges of the can caps X. The connectin chute K and strippers K areso arrange and combined with the carrier G and cap holders F thatthecaps as they are freed from the holders slide down the connectingchute with their freshly coated faces uppermost.

The drier M referably consists of a long horizontal heating chamberfurnished with gas burners or other heaters-m and having atop plate malong-which the coated caps are conveyed by a flexible or endless chainconveyer M traveling on pulleys or sprocket wheels M the links of thechain being furnished with cross bars m adapted to engage the can capsand shove them along the heated top plate of the drier. The connectingchute K is arranged at an acuteangle to the top plate and conveyer ofthe drier so that the freshly coated caps will the same without dangerslide directly onto of being turned over. The conveyer M is preferablyintermittently operated by a step by step movement by means of a crankarm m on the shaft S through a connecting linkm, pawl lever wa havingpawls 'm -en- I a ratchet m" ofi the shaft m. of one of the conveyerpulleys M Each of the va ves or devices P for automatically regulatingand controlling the amount of liquid lacquer or coating material sprayedupon the mner face ofeach can cap, 1s preferably automatically operatedI30 cap feeder, a can cap lifter, a series of magoverflowing li uidlacquer is returne the supply tan N is preferably operated by means ofan eccentric N on the shaft S and which is connected by a link N withthe iston' rod N ofthe um T e li uid supply ta-n N is preferablyfurnishe with an agitator or stlrring device T which may preferably beoperated by a connection T from the piston of the P P- a 1.
